Signing Modules with mokutil

shreyashah1903 — Wed, 29 Sep 2021 05:22:04 +0000

This blog focuses on installing Nvidia driver and few other drivers using the mokutil signing functionality.

1. Create a pair of key on system to sign the modules.

openssl req -new -x509 -newkey rsa:2048 -keyout /home/user/Nvidia.key -outform DER -out /home/user/Nvidia.der -nodes -days 36500 -subj "/CN=Graphics Drivers"

2. Add the key (Enroll using mok)

First command will ask for a password. After reboot enter the same password. (** Prompt will ask for characters in specific position of the password. Do not enter the whole password. **)

sudo mokutil --import /home/user/Nvidia.der
sudo reboot

Check if keys are enrolled

sudo mokutil --list-enrolled # or sudo mokutil --list-enrolled | grep -i Graphics

3. Update the dkms sign file if adding using dkms

Updated the /etc/dkms/sign_helper.sh. Add/update the line with the newly created key paths.

/lib/modules/"$1"/build/scripts/sign-file sha512 /home/user/Nvidia.priv /home/user/Nvidia.der "$2"

Update /etc/dkms/framework.conf Uncomment the line where sign_tool is mentioned

sign_tool="/etc/dkms/sign_helper.sh"

If you have already added dkms modules before changing the sign file, first remove and then add them again.

sudo dkms status # Check status of dkms module
sudo dkms remove <module>/<version> -k <kernel_version>
Eg. sudo dkms remove hid-asus-rog/1.0.2 -k 5.10.0-8-amd64
sudo dkms status # Check uninstalled again
sudo dkms add . # in the cloned directory of dkms module
sudo dkms build <module>/<version>
sudo dkms install <module>/<version>

4. Installing Nvidia driver

For installing Nvidia driver using the .run file and enrolled keys. Get-the-Driver-here

sudo sh ./NVIDIA-Linux-x86_64-460.73.01.run -s --module-signing-secret-key=/home/user/Nvidia.key --module-signing-public-key=/home/user/Nvidia.der

If this does not work try removing -s from the command above.

Install Debian Series (Part -1 Creating Recovery drive and a bootable drive)

shreyashah1903 — Wed, 29 Sep 2021 05:11:10 +0000

Introduction

The series focuses on installing Debian as a primary OS and removing Windows/ formatting Windows.

Part - 1 focuses on creating a recovery drive and a bootable drive.

Prerequisites

Wired Internet connection (Wired is preferred as the wireless drivers have to be added as part of installation)
One USB flash drive (atleast 16 GB in size) if you want to create a Windows 10 recovery drive
One USB flash drive for creating a bootable media to load the Debian OS.
Of course a laptop.

1. Creating a Windows Recovery Drive / System Repair disc

The recovery drive will store Windows OS with the system files which will allow you to reinstall Windows again at a later point in time. Consider the recovery drive as a factory reset/Wipe data option in a mobile phone nowadays.

Any personal files or applications will not be backed up in the recovery drive. For that, you need to do a system image backup which will backup everything. System Image Backup will require an external hard drive as it is a large file. For eg. If you have a 1TB hard drive with 100 GB of used size, the system image backup will almost be about 100 GB in size.

Steps

Insert the formatted/clean USB flash drive which is at least 16 GB in size. The steps below are done for Windows 10. It might change a little bit for other versions of Windows.
Press Windows button + S. Type Recovery Drive.
Back up system files to the recovery drive checkbox. Keep it checked.
Select the USB drive once it appears. Click next.
Get a snack, this will take sometime to finish.
Click finish and store the USB at a safe place.

2. Creating a bootable USB flash drive for Debian

Download required ISO (*.iso) file for Debian from the here.
Download the Rufus software from here. This is a helper software to create a bootable media.
Insert a formatted USB flash drive and open Rufus.
Select the USB flash drive in device.
Select the ISO file.
[optional] Give an appropriate Volume label (flash drive name).
Keep everything else as default option.
Click start and click close once it is ready.
